Analog and Mixed-Signal Extensions—Packages for Multiple Energy Domain Support Overview 1.1 Scope This standard defines a collection of VHDL 1076.1 packages, compatible with IEEE Std 1076.1™-1999,1, along with recommendations for conforming use, in order to facilitate the interchange of simulation models of physical components and subsystems The packages include the definition of standard types, subtypes, natures, and constants for modeling in multiple energy domains (electrical, fluidic, mechanical, etc.) The packages are intended for use primarily in the modeling of multiple energy domain systems The range of operation of the packages is not defined in this standard, but is intended to be valid across a wide range of disciplines and applications This standard is embodied in the package declarations for the following packages: ⎯ FUNDAMENTAL_CONSTANTS ⎯ MATERIAL_CONSTANTS ⎯ ENERGY_SYSTEMS ⎯ ELECTRICAL_SYSTEMS ⎯ MECHANICAL_SYSTEMS ⎯ RADIANT_SYSTEMS ⎯ THERMAL_SYSTEMS ⎯ FLUIDIC_SYSTEMS

Analog and Mixed-Signal Extensions—Packages for Multiple Energy Domain Support 1.2 Purpose The definitions of IEEE Std 1076.1-1999 allow users to build simulation models of physical components and subsystems that may belong to multiple energy domains (electrical, fluidic, mechanical, etc.) Such models are built upon sets of properties that are specific to each energy domain and encapsulated in socalled natures IEEE Std 1076.1-1999 provides a mechanism to define natures, but intentionally does not predefine any standard set of natures as it is expected that this would be done in a subsequent IEEE standard project The definition of a standard set of natures is crucial to make possible the reuse and exchange of models written in VHDL 1076.1 within and among vendors The packages were chosen for two purposes The first purpose was to define a set of basic physical constants (either with or without default values) so that models written using these packages could have a common basis for modeling physical systems The second purpose was to define a set of types and natures that would provide a common framework for modeling physical systems across a range of commonly used energy domains These purposes enable models written using this standard to contain the same physical constants, but also ensure that the interfaces are consistent, correct, and maintain interoperability 1.3 System of units The International System of Units, universally abbreviated SI (from the French Le Système International d'Unités), is the modern metric system of measurement, and is internationally recognized The SI system of units is used in this standard to ensure that the packages are consistent, correct, and internationally interoperable In practice this means compliance with IEEE/ASTM SI 10™-2002 Due to the inclusion of machine readable text in this standard, it has been necessary to use mathematical notation using the syntax adopted by IEEE Std 1076.1-1999 This is a specific exception to the general SI usage in this standard 1.4 IEEE math package This standard uses the VHDL mathematical packages in IEEE Std 1076.2™-1996 for the definition of basic mathematical types and operators Definitions For the purposes of this standard, the following terms and definitions apply The Authoritative Dictionary of IEEE Standards, Seventh Edition, should be referenced for terms not defined in this clause 2.1 unit: Attribute defined as a string that is used to define the name of the fundamental unit of the declared type For example, for the quantity voltage in electrical systems, the UNIT is defined as "volt." 2.2 symbol: Attribute defined as a string that is used to define the symbol of the fundamental unit of the declared type For example, for the quantity voltage in electrical systems the symbol is defined as "V." Constants The constants shall be divided into two classes: fixed and user-definable The fixed constants shall be fundamental physical constants that have accepted values The user-definable constants shall be defined as deferred constants, allowing them to be defined in a package body by the user This allows the package to contain names of commonly used constants, without restricting the value to specific cases The constants package shall use the MATH_REAL package from the IEEE library Copyright © 2005 IEEE All rights reserved IEEE Std 1076.1.1-2004 IEEE Standard VHDL Analog and Mixed-Signal Extensions—Packages for Multiple Energy Domain Support 3.1 Usage The FUNDAMENTAL_CONSTANTS package shall be compiled into a library symbolically named IEEE The MATERIAL_CONSTANTS package shall be compiled into a library symbolically named IEEE_ENV 3.2 FUNDAMENTAL_CONSTANTS Copyright 2005 by IEEE All rights reserved - This source file is an essential part of IEEE Std 1076.1.1-2004 IEEE Standard Packages for Multiple Energy Domain Support - This source file may not be copied, sold, or included with software that is sold without written permission from the IEEE Standards Department This source file may be used to implement this standard and may be distributed in compiled form in any manner so long as the compiled form does not allow direct decompilation of the original source file - This source file may be copied for individual use between licensed users This source file is provided on an AS IS basis The IEEE disclaims ANY WARRANTY EXPRESS OR IMPLIED INCLUDING ANY WARRANTY OF MERCHANTABILITY AND FITNESS FOR USE FOR A PARTICULAR PURPOSE The user of the source file shall indemnify and hold IEEE harmless from any damages or liability arising out of the use thereof - Title: Standard VHDL Packages for Multiple Energy Domain Support -(IEEE 1076.1.1–2004, FUNDAMENTAL_CONSTANTS) - Library: This package shall be compiled into a library symbolically named IEEE - Developers: IEEE DASC VHDL Multiple Energy Domain Packages Working Group - Purpose: To define a set of basic physical constants with default values - Limitation: - Notes: The fundamental constants used in this package were based on the -National Institute of Standards and Technology (NIST) values with -published uncertainty as given in the table below: - Constant Description Default value Uncertainty - PHYS_Q Electronic charge 1.602_176_462e-19 0.000_000_063e-19 -12 PHYS_EPS0 Permittivity of vacuum 8.854_187_817e exact PHYS_MU0 Permeability of vacuum 4.0e-7*pi exact PHYS_K Boltzmann’s constant 1.380_650_3e-23 0.000_002_4e-23 PHYS_GRAVITY Accel due to gravity 9.806_65 exact PHYS_CTOK Convert degrees C->K 273.15 exact PHYS_C Velocity of light 299_792_458.0 exact PHYS_H Planck’s constant 6.626_068_76e-34 0.000_000_52e-34 PHYS_H_OVER_2_PI Planck’s constant/2*Pi PHYS_H/MATH_2_PI 0.000_000_82e-34 - - Version : 1.0 Date : November 2004 Copyright © 2005 IEEE All rights reserved IEEE Std 1076.1.1-2004 IEEE Standard VHDL Analog and Mixed-Signal Extensions—Packages for Multiple Energy Domain Support library IEEE;
